If it supposed to work the way I think, you are missing some seal ins to keep you brew/clean light on.
and as of now I will assume you have to hold the button down to keep the light on.
also with your setup as long as one light is on the other can never come on, without turning it off, which i will again assume is not what you want.
I suggest looking up flip flop, this site is an awesome resource.
and iron_will timer suggestion is a good one so you will actually be able to see what is happening.
